-certain new and useful Improvements in Resilient Wheels, of which the following is a specification.

The present invention relates to resll- 'ient wheels and forms a division of our copending application for improvements on resilient wheels filed June 29, 1914. and bearing Serial Number 848,018, patented Aug.l

-The invention has for its purpose to provide a wheel 'having means associated with the hub thereof which serves both as the resilient medium andl shock absorber lfor the vehicle, and wherein all motion incident thereto is transmitted axially of the wheel, to the endof obtaining substantially complete flexibility with maximum rigidity of wheel structure.

The invention has for its further purpose to provide a novel form of driving connection between the ,wheel hub and wheel proper to the end that there will be perfect resiliency between these parts; and wherein the connecting medium is of simple and durable construction, and which will in no manner interfere with the normaly resilient function of the wheel.

Another object of the invention is to construct a novel form of wheel-hub chamber containing the resilient mounting for the `wheel andy wherein the hub elements` are themselves rigidly securedJ together -wholly outside of said chamber.

f The invention' is shown by/way of illustration in the accompanying drawings wherein:

Figure 1 is a side elevational view thereof, and with parts in section for clearness. Fig. 2 is a central sectional view of the same, and Fig. 3 -is a detail view of one of the hub connections.

Referring to the construction in further detail and wherein like characters of reference indicate corresponding parts in the different views shown 3 represents the spokes Specification of Letters Patent.

of -the lwheel and which at the center unite in the form of4v a disk 4, and which disk together with said spokes will hereinafter be referred to as the"rim ofthe wheel.

. The wheel hub comprises two members, or parts 5 and 6 which areomounted on the axle (not shown), and are constructed with side plates 8 and 9 respectively. Said plates 8 and 9 are formed with inturnled edges disposed to have free contact or engagement with the opopositefacesv of the rigidrimV ortion 4, vas clearly shown in Fig. 2. aid hub plates 8 and 9 are substantially of concavo-convex design in crossss'ection and form a substantially complete inlosure or housing for the wheel resilient elements contained therein. y'

A pair of sleeves land to have axial movement on the. hub sections 5v and 6 within the housingand said sleeves are formed with cone, heads 17 and 18 re..

spectively. The conical surfaces of said coneV heads bea-r in contact with the relatively -angular facesformed on the rim 4, and a pair of springs 21 surrounding said sleeves hold said cone heads in resilient contact vwith the rim and form a floating suspension or bearing therefor after the.man. ner described 1n our co-pending application"- heretofore referred to. l

The hub sections 8 and 9 are rigidly united by a plurality of pairs of/radially disposed' lugs 54, havin ribs 55,'connected by bolts 16 are mounted 56, provided with securing nuts 57. A spacing member or collar 58 is fitted on each of said bolts between each pair of lugs. y

' The connection between the rim and hub consists of a floating ring 59 arranged concentric with the axis of the hub and secured to said rim by a pair of diametrically opposite links 6() having pivotal engagement with the ring and rim b'y pintles 62v and 63; and a similar pair of links 6l connect 'said rim with the h ub plate 8. TheY links 61 have pintle engagement at 64 and 65 with said ring and hub plate as in theformer instance. `The pintle 65 of the arm 6l has pivotal connection with the hub plate 8 by a boss 65a on said hub plate. (See Fig. 2). `Said links 60 and 61 are curved concentric same central plane ot the wheel, and it 1s withv the floating ring 59 and are located immediatelyv adjacent said ring for their respective lengths, thus bringing the several pivotal centers of the links equidistant from the axis-'of the Wheel and thereby the driving element forms a compact unit of restricted dimensions.. of the side plates against the rim portion of the Wheel are at points appreciably remote from the axis of the wheel, and the points of radial suspension (i. e. the contacting surfaces between the cone heads and the wheel rimv portion 4) and the lateral sustaining means (the rim bearing;` portions of Athe side plates) are located in substantially the this disposition of the parts that contributes in a great measure to the practical operation of the'device. l

From theforegoing it will be seen that the `connection between the hub plates is'located entirely with-out the hub chamber: and the I connection b etween the rim and hub is sut'- iiciently flexible .for allowing freedom ot movement of the riinwith respect to the 4cushioningor sustaining;element and vet i in view.

Having thus described our invention what rThe bearing portions we claim 'as new and desire to protect by UnitedStates Letters Patent is:

1. In a resilient wheel, the combination ofa hub having rigidly connected side plates; resilient members associated with the hub a wheel rim portion in the plane of the .Wheel `tread,radially lsustained by said resilient elementsv andlate'rally snstained by the side plates; and a flexiblel driving connection located between one of said side plates and said wheel rim portion; said driving connection comprising a oating ring and two pairs of diametrically opposed links' curved concentric with the ring and connecting said ring with said rim and the side plate, substantially as described.'

2. In a resilient wheel, the combination oi a hub member; a rim member radially movable relatively to said hub member; one of said members having a lateral extension bearing against ,the other of said members and thereby sustaining the rim member laterally b v the hub member at points appreciably remote from the axis ot' the wheel; a resilient means sustaining the rim member radially, said radial sustaining means and the lateral sustaining means being located in substantially the same central plane of the wheel located between the hub member and the rim member; and a tloating drive vconnection also located between said hub member and rim. member and connected tov both of said members.

in testimony whereof we aiiix our signatures in Vpresence of two witnesses.
